26.2. AbBind.writeFlat(): Write an abbreviations
file record

The purpose of this method is to write a flat record to the
abbreviations file. It is guaranteed to work only for codes
that are related to a specific taxon, and which are derived
from specific English names. In practice, this means that the
.lookup() and .eng() methods
must return strings. In the current implementation, derived
classes StdBind and EqBind use
this method. The CollBind instance overrides
it, because it uses a different format and writes to a
different file; see Section 29.6, “CollBind.writeFlat(): Write a collisions
file record”.
